Two people have died and 25 people injured, four seriously, in a large fire in the French ski resort of Courchevel.

The fire broke out just before dawn in a building in the heart of the Alpine village where seasonal workers, including foreigners, were staying before spreading to two other buildings.

More than 70 firefighters were involved in bringing the fire under control and 60 people were evacuated.

Three of the four injured were flown to hospital by helicopter, but are in life-threatening condition.

French Interior Minister Christophe Castaner tweeted his condolences to the families of the victims. The Savoie prefecture said the Albertville prosecutor has opened an investigation into the cause of the fire.
